How to find old post?

You can try using google
https://forums.d2jsp.org/topic.php?t=71037750&f=34

or if it's your post you need, you can pay 5 fg to search all your posts in a specific sub-forum
https://forums.d2jsp.org/index.php?act=Search&t=1134005

If you know the forums you can browse manually through the pages, sometimes years back depending on the forums. You could also search a friend's account that you know posted in the thread you're looking for and might be luckier that way.

Hey! Thanks for the link, Phyerox. It was hard to find old forums before.

Thank you!
