The VPA had to install a new web site script because the other was just not supporting our needs and was too easy to spam. We have installed a much better system and we will be moving over data that we can from the old site. You will need to register again to gain access to the new site. Sorry for the trouble but the spammers forced our hand.
I hope that Dolphin has improved their security enough to prevent the spam.
In the years that I tried to use it from concept to two years ago, they had not.
I would suggest hiding the Dolphin info in the public portions of the site as well as the version.
I know this may be just something that you have not had a chance to do yet, but it does give potential hackers a starting place. Especially since the Dolphin code is easily available for modders.
