Animating in pivot will grant you a lot of respect by the community. Everyone will look up to you for creating a pivot. Forget about those baby programs like easytoon, or Adobe Flash, cause you're animating like a REAL animator.

Use of pivot is highly not recommended, so heres a list of download links for the program.

Or, the.. "better" version, pivot 3 and 2.5.5 mixed. Creds to SoulEater for originally posting it.

Quote from SoulEaterCredits to darkdemon for taking the time to mod pivot.
-It has the features the same as pivot 2.5 and 3, and no read-me message, it -has the pivot 2.5 base stick and pivot 3's frame editing system
-The frame rate can be higher, allowing smooth animations
-Gif. Saving system has new options
-This version works on both 2.5 and 3 beta sticks
-The screen size editing was modified to save each repeated frame as a bitmap.
-It can still load sprites, and with less lag
Make sure that when you save a gif. put the frame delay around 6
There could be more benefits that are in this that I forgot, but I'll be updating the post for everything that I discover which makes this a good program to use, the link to download is below.

I bet that this will end many quarrels about which is better, pivot 2.5 or 3 beta, because I think that with both of them put together, it makes a way better animating program compared to 2.5 or 3 by itself.
