So I accidentally deleted my RSS feed, how do I get that back?
I also noticed I changed my username and heyjaywilson.micro.blog (current) is not valid but maeganwilson.micro.blog (old) is still valid. I made the change a few days ago. Will it be updated?
In which way have you deleted your RSS feed, and which feed are you talking about? From what I can figure out, your blog is heyjay.coffee and the feed is located over at https://heyjay.coffee/feed.xml.
The subdomain(s) your blog(s) reside on are separate from your username. When you create your first blog at Micro.blog it will be hosted at yourusername.micro.blog as a default, but it can really be anything as long as that subdomain is available.
Changing your username will not affect the subdomain your blog is at. Unless you explicitly ask @manton to change that as well by sending an email to help@micro.blog.
