YATTA! You will be glad to know that the Top Commentators Widget is bug-free! Or at least I hope so.
Blank fields now have default values even if you didn’t fill in a thing; values are trimmed, htmlspecialcharsed, stripcslashed, exploded, and stuff. For those of you who have been using the control form version a.k.a. version 0.9, most of the bugs had appeared when any of the fields was left blank. This and a lot more have been addressed and dealt with in version 0.99. 0.99 because I think it still needs some testing out by someone other than myself, which means that you will be sacrificing your blog by risking the upgrade ;D
So, yeah, download it now. In the mean time, I’m off to finish up my WP 2.2 upgrade.
