Welcome friend! Happy to have you here.

Just a note on terminology, but subreddits are called communities here (hence the c/ in the url), not feddits. Also, the software this place runs is called Lemmy, so most places discussing it will have Lemmy in the name not Feddit. For questions about here there’s !newtolemmy@lemmy.ca or !lemmy_support@lemmy.ml, but feel free to ask questions here or on !feddituk@feddit.uk and people will normally be happy to help (including myself).

Is there a Feditt to ask if there are existing feddits, like r/findareddit?

!findacommunity@lemmy.ml or you could ask in !communitypromo@lemmy.ca which is more active.

Is there a Feddit to discuss Feddit Apps?

!lemmyapps@lemmy.world. To find apps https://join-lemmy.org/apps has a list of apps with filters for platforms. I’m not an IOS user, but I’ve heard good things about Mlem.

Can I edit/change my username?

You can’t change your username, but you have a setting called ‘Display name’ which can be changed and will be what shows up in most places, e.g. my username is flamingos but my display name is flamingos-cant which is the name you see.

Sorry for all the edits & questions, I’m like a kid in a sweatshop, this Voyager App is the closest U.I. to Apollo for Reddit & it feels like I’m using Apollo.

I don’t user Voyager myself, but I’ve heard it very good. Certainly can’t go wrong with it.

I’ve brought some Hobnobs with Chocolate on…

Trying to curry favours with the admins I see. It’s working.
