If you have your own website, you can give Roster a try with the Siggen addon for it. Through the config menu you can change the signature to look damn near anyway you want and update it as frequently as you care to.
All that is required is:
1) Characterprofiler and Guildprofiler addons from RPG Outfitters

2) Roster website software from

3) Siggen Addon for Roster
