No, there's not. The tag fairies read the boards like the rest of us do...and when they see something that catches their eye or makes them chuckle, then they tag away! They especially delight in taking rather embarassing quotes from your posts and putting them in your tag!
Since you have to post to be read, the best way is to actively participate in the boards!! But don't get upset if you go for awhile without a tag....some folks have been here years and have yet to get a tag...
Oh, and they prefer not to be begged. It's supposed to be spontaneous and fun for everyone....and they get stressed out and don't come out to play as much if everyone is begging and asking for tags!
For KBFinFan....Your tag is the words under your user name. Once you've been here awhile, you can change your own tag (after 75 posts, I think). But only the tag fairy can put it in color! You never know when....you log on one day and there it is...a little color to brighten your day! A word of caution....if you DO get tagged, don't try to change it unless you want to lose the whole thing!
Welcome to the DIS and post away!!
