I am sure you have done this for the right reasons.

From a personal perspective, I have not contributed, although have posted elsewhere. As much as I would like to contribute, I have nothing at the moment that is suitable.

As mentioned on one of my other posts, I have tried to develop a plates in shear calc, but am currently stumped. If I could get past this, you would have the calc.

Keep up the good work with the site, its certainly interesting, and more importantly, useful.
