I saw a post today about someone looking for people from his old guild in EQ. Now, while one post isn't bad, I'm sure there will be plenty of other posts as soon as people start finding this board.
My solution, should you choose to keep bumping it, is to try to confine all the posts of people looking for old friends in one thread. I know it probably won't happen, but if we can keep the majority in one convinient place, they're less likely to get lost in the mix.
The minimal amount of info you should have is character name, server, and guild. Post that info first so that people can easily see it and skip your post if they don't know you. Then post a short paragraph, if you want, but keep the info stated above first.
I'll start with an example below.
