I think we all have no problem to grasp the essence of this forum : A tool for us players and DMs alike to use so we can fill the gap that forms when two or more players can't be online at the same time, but still want to participate in the multitude of storylines in developpement on the server.
That aside, my main point with this topic is bringing the discussion on one particular detail, a little one some might say, but of great consequences.
Unsigned Notices
While to some of you, it may be well-sounded to leave an extensive and well written notice unsigned to add to the mystery of it all. It really don't. What if my character comes by this notice, and find it an interesting plot hook, and want to participate? In this case, it is not easy for the character to pursue in this venue, unless he wishes to spend a lot of time in-game to hunt down the poster of the notices, and that, to most of us, isn't fun.
When you are spending time to write a note with some background elements, some information that you spent considerable time researching in game, do yourself and the rest of the server a favor, and sign your note. It will help immensely in keeping the storyline going on and people will want to interract with you more, which is the main goal of the server, getting some interraction going.
If you are truly concerned about not being recognized or immediately associated with said poster, sign under a false name, or an alias, or with a code. That will help the players that may want to learn more on what you posted about and will leave them with an alternative to spend lots of boring time looking for you, like sending a letter to all the inns with your alias or sign name in the destinator field.
In short, help you to help us, and sign your notes.
