I'll try the blog link as a workaround, thanks. If possible, I'd still prefer the functionality described by Philospher and was just about to post pretty much the same request.
Since the forum prompts us to include system specs in every post, if we've taken the time to fill it out I agree there should be an option to reuse or autofill that info. Making it hidden and expandable is a great idea too. This would save space as suggested while still making it quick and easy to glance at system specs. By comparison a blog link opens a whole new tab or window which will become tiring after while. Another disadvatage (or advantage depending on how you look at it) of a blog post is that it's unstructured while system specs is a structured record.
Other suggestions/requests for system specs: (1) Change the label "CPU Pps:" to "Purpose:" and (2) add a field for Case. BTW, I want to say the EggXpert site is awsome. These are just a few small wishes from some of your newest fans!
