Just in case you didn't know this - on Cohost, you do not need multiple accounts. You can create "pages," which are, for all intents and purposes, your alts - they look, act, and interact like separate accounts, but all your settings (content preferences, tag whitelists, etc.) are managed in one place for all of your accounts. That little drop-down in the upper right that shows your username has a "(+) create a new page" option that you can use to create your alts. You can't actually do that until you've been activated, so if you're still in that pre-activated queue, just hang tight and you'll be able to do it as soon as you're active. The cool part about that is that you don't have to wait for your alts to be activated - once your account is active and you're able to post, you can post from ANY of your pages.
I already have two alts myself: @MerakBurr (for non-ABDL content) and @RhettYeen (my private account; don't request a follow there unless we're good friends), and both were able to begin posting as soon as I created them.
I hope that helps! I know lots of you are Twitter refugees like me, so I'm trying to pass along all the helpful stuff I discover about this site as I find it. Pass it on so others can see it too!
