It's my Win VS. I don't know, but i think Pidgin hasn't got skinning captabilities.
You are always welcome Sasha
Thanks for your answer Rafel, I appreciate your prompt respond.
I just found out that along with Pidgin, you can install GTK +/Win32 Theme Selector. Themes are pretty simple, most of them kind of Linux looking, but it's better than nothing. The only thing is, once you start GTK theme selector and pick your theme you want to use, you will have to completely shut down the Pidgin and restart it in order to see the change.
I love this little chat program, it's simple incredible how light it is, and how effective it is... it does everything it is supposed to do, and I have to say a lot better than many of those multi-protocol clients. Above all, it is not bloatware which is the case with most of chat clients of this kind.
And all those protocols it supports, simply wonderful!
