For a period of time - not precisely sure how long - there is a tab showing at the bottom of your post that says 'edit'. If you click on that it will reopen the initial post so you can make changes or add to it. After any changes or additions, you hit 'submit' again to repost.

This is the same with the 'delete tab. It is only available for a limited period of time

I think that you have about an hour to edit the title.

My experience with my phone is that the "edit" and "delete" options on which one can click are on the line at the top of your post where your username shows.

I think that I've sometimes been able to edit after two or three days; sometimes maybe more?

The deep green "Submit" line fades to light green when your offering has been posted.

If you inadvertently try to leave the thread before your message has been posted, you'll get an "are you sure?" message.

The difference in placement may be phone vs laptop or computer. I never use my phone for accessing the site.....I just don't care for that function and it is too small to see anything clearly on screen. And I only access through GardenWeb as well, never Houzz. That could also make a difference as the two platforms are far from being properly sync'ed.

"I think that I've sometimes been able to edit after two or three days; sometimes maybe more?"

Right...I've noticed it remains for at least a few days.

Responses can be edited days after they are posted, but the original post has a very short time (perhaps an hour) that it can be edited, but I don't know the rules for deleting the entire thread. I deleted a post that I started once, but it was less than an hour after I had posted it, and no one had responded yet. I deleted it because I had found the answer I wanted on my own, but people had already read what I had written and were trying to find an answer for me. Therefore I started a new thread and apologized for deleting the original thread, and I also posted what the answer was that I was looking for, in case someone else had the same problem. This had to do with thermostats.

I also don't use my phone for the reason gardengal mentioned. I do access via Houzz.

Just checked a couple posts I made. Looks like you can edit/delete for at least 5 days after posting, but definitely not as long as 8 days.
