When I text it shows my email

Go to Settings —> Messages —> Send & Receive.

“You can receive iMessages to and reply from”: should already be defaulted to your phone number. You can also chose whether or not you want any other of your emails to send or receive iMessages.

Set “Start New Conversations From” to Your Phone Number.

Sometimes posts don't show up right away, until another post to the same thread is made. Today that has been a recurring problem. If you see a post with only a period (.) in it that is to force an invisible post to appear. That's sort of a convention used by forum regulars.

Go to Settings/Messages. Tap on Send & receive. Check however you want under Start New Conversations From.

Note that this will not change existing conversations that are in progress.

Isn't in nice when you get to answers to a question and they agree? 😉

I didn’t even see your post when I opened this conversation. Well great minds think alike at least.
