Okay, I have an idea but I have come across a hurdle. I am looking for a Wiki which is math friendly where it is relatively easy to write a formula, square root etc. Basically, anything that Equation Editor can do. I did find LaTex Equation editor which says it is a Gadget (same as Widget) but the Wetpaint Wiki which I tried says that it does not support this script. Any ideas or example of Math Wikis?
