Hey,
I think the Members directory (newly added by Saed, thanks!) in the right side bar, which gives access to all registered members is the right place to list all our alts.
I’m going to update mine straight away ;).
Also, this council has now made it mandatory to list our alts (or at least your main, or a common reference, like Hagenti does) in the note field. We did that a few months ago, following some misunderstanding. There was an in-game mail, but we should have posted the change on the website too.
