I actually used to be a moderator on a well known forum among ABDLs for over a year. That particular website is aimed more towards support for ABDL and incontinence related issues, rather than targeting the more sexual side of the fetish.

I came to the site more so due to having incontinence issues, since I found incontinence support forums to be some what depressing. I found being around people that had more of an interest in diapers to be more comforting than being around people that only used them due to medical needs. I find there is more of an up beat attitude among ABDLs with regards to diapers.

Like many of the people on the site with incontinence issues, I have grown over time to have a DL interest. I find that it does make a good coping mechanism too. I however don't have an AB interest, but I now have many friends that do.
