I get the same message, it seems I can't like any mods or posts in mod threads made before the system came online.

We will look into the issue of not being able to like those posts. I'm not sure what is up with that. I'll put on my coding hat in a bit and take a look. :)

edit: Right now we have it set so you can only Like open threads that are less than 180 days old.

Sorry for buggin' ya, but is it going to stay that way, or might you plan on changing it?

I understand there's a reason for the time limit n' all, but there's a lot of posts older than half a year which deserve thanks (IMO, anyways). Case in point would be the modifications that have been out for longer than 6 months.

You're not bugging me by asking. :)

It is up for consideration. I can't guarantee that it will change, but I have brought it up with Staff.

What I would have liked is to get notifications when someone likes your post. Please see if its possible to do that. :)

That would be a very nice addition. Hopefully they will take this into consideration.

I dunno about Notifications, but if you look in your profile, you can see the latest likes you received. (Sorry if you already knew about that feature; if not, now you do. :>)

Seems like reinventing the wheel to me. What was wrong with Abe's like mod, or one of the other similar ones that use Ajax?

Where can I "unlike" a post? I have liked the opener of this thread but would like to undo that action now?

Actually, the Thanks Hack was reinventing the wheel. We simply modified the rep system that was in place to do what we wanted.
Just like with the rep system, you cannot take away the Like.
