Hmm. here are my thoughts on this. The server forum is for the whole server. If we sticky something for just one linkshell then it could possibly be construed as favoritism or endorsement.
Now if it were a generic "links to linkshells on Sylph server" thread, that I wouldn't have a problem stickying.
Of course that is just my oppinion. One of the other admins may have a different view on it of course.
