Welcome to Mantis Study Group
Mantis Study Group Website.
The scratchpad system has changed (yet again) and messed up the website completely. Changes are so frequent that I have given up trying to maintain the site. Try searching for any content you'd like to find - it may be there, but only available via a search.
Don't try to log on - that aspect is no longer active and, due to the system changes, I do not know how to remove it.
