This mod doesn't really have anything to do with the sidebar mod.
This is an addon (like the other addons included with threads) that you can include into a regular php page - and there's a Pal box to act as one of the custom boxes in IIP.
We used the sidebar mod here the whole time we ran 6.2 - so it'll work just fine. However the instructions that I have released were written for 6.3. I didn't want to waste my time writing instructions and trying to support for a old version. So I usually post stuff for the latest version.
If you've had a good bit of experience applying hacks to threads - you could adapt it to 6.2. But I'm sure you'll want 6.3 eventually.
If you needed to run it under 6.2. Myself or one of the other
Developers for Hire could be enlisted to install this into 6.2.
