The only gotcha is that it chokes on Tweeple who have their Twitter profiles set to private. We put a notice in the plugin edit page telling members not to use it if they are set up that way. This seems to have mitigated the problem.
It is also VERY important to give members VERY SPECIFIC directions on how to find and then enter the Twitter account number. They got this wrong every way possible.
Would be nice if there was an option not to show the Twitter name (redundant) and account number, (pointless) to other members.
The only need is a bit more flexibility in the css styling. Sobi2 offers a good example of how to do field level styling.
Great work thank you!
