I'm quite new here. I have a Petr_M account here and asked one question in the past. Now I wanted to ask my second question but when trying to sign in, I was asked about my username. So I filled in PetrM and asked my question. Only after getting my 1st topic badge (again), I realized I've created a new account. I would like to delete this account, but had zero luck trying to understand how to manage these two identities of mine. If I sign out and then sign in again, I'm not given any choice and am just signed into this new account.
If this question belongs somewhere else, please let me know.
