Unable to edit post

Hi all,
thank you for the amazing work you have been doing with this site and the community.

My issue is I cannot edit a post I originally made a couple of days ago (for reference, this post). I would like to be able to edit it indefinitely because we are using it to collect standardized translations of terms for the course, to ensure consistency between the different chapters in the italian translation.

In general, I think other sites allow editing of posts without a time limit, is there any reason why you disable it?

Thank you very much!

It seems that Discourse puts a time limit on editing posts, because I now see that users with trust level 2 are able to edit their own posts for up to 30 days. I only have level 1 apparently, so is there anyway that this could be changed?

Thank you!
