Can't edit first post in my thread?

I thought the time limit on editing any post was 10 minutes, but maybe not. Someone else should come along and might offer some help. But if you'll post the URL of the thread whose title you want changed and what you want it changed to, I'll change it for you.

Oh thank you! Yeah that seems to be the case since I can't edit this one now but i could right after i posted it.

This is the thread
https://www.guineapigcages.com/forum/pregnancy-babies/77175-question-about-pregnant-rescue-pig.html

I would like to change the title to 'Izzie Pig Pregnancy Updates'

It's changed.

Thank you so much!
