Nutrinopets 

A relatively small and new virtual pet site, this site only has around 20,000 users or so. Although complaints have been made about the terrible economy, the influx of Nutrinocredits far higher than the amount spent, the site has a very proactive team of staff who work hard to remedy all problems. Changes are made on an ongoing basis. Recently, the layout has changed, the pet system has been completely revamped, as well as many new changes.

Part of the uniqueness of this site is that it values user input a great deal. There is a special forum called "Suggestions", where users can pitch in opinions and ideas. The best opinions get sorted into a staff forum, where they are eventually used at some point. Also, selling self-made art and trading self-made art is allowed, even encouraged, as there's a forum specifically for that, drawing many artists to this site. Many pieces of art often go for millions of NC.

The users are exceedingly friendly. Many a person has commented on the forums about how no person ever scams, how spam hardly ever appears in the forums and the general politeness and willingness to chat of the users.

Although comparisons have been made between Neopets and Nutrinopets, Nutrinopets actively work towards dropping that comparison. The users and staff firmly believe that they are different and that the only reason why such comparisons have been made is that Neopets, being the most successful site in terms of user numbers, is seen as a goal for most pet sites.
A Nutrinopets user, rather than scorning a newcomer or a n00b, politely debunks him.

Example:
N00b: Lol! how can i earn monies?
Nutrinopets user: There are a variety of ways... (lists ways)

ON OTHER PET SITES...
N00b: Lol! how can i earn monies?
User: Gawd, you're stupid! Go play some other game, you don't have a right play this game.

A dead drop is a location used to secretly pass items between two people, without requiring them to meet.

Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.

A common place is to duct tape the item to the underside of a toilet cover in a public restroom.

A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."

No Surprises Wedding

A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.

This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.
You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.

Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.
