who do i contact regarding difficulties changing my default e-mail address (old yahoo account) to my current main one (gmail one). However, apparently I have had used my newer e-mail account to create a profile since I cannot switch my default e-mail to the new one.

Please let me know asap cause I really want to be able to get notification of replies to my threads.

I cannot find out what username I had created with my gmail account. I dunno what happened to it and I tried to send the user/password request to my gmail account several times and still haven't gotten anything. maybe I can request that someone can force a message to my gmail account (that way you'll know that I'm the owner of the gmail account by getting to my user via the e-mail there.)

PM me and I'll send you my e-mail address for you to send the user/password reset/notification to.
