I do NOT like the H2@home participation << by invitation>> associated with Boinc. It simply sucks too much. It remind me some kind of fraudulous overseas financial services only offered, <<by invitation>>... Relics from another era. Either you ought to open account creation as other project use or you keep it loud. I would definitively not shout it out as "missing in invitation"...
We are all entitled to our opinions, but you have to understand I am the only developer on this project and I say that in the looses sense possible. I have no formal training in web development and I am learning as I go. Sure if it was a full time job, or I have additional volunteer admins who knew what they were doing then we would enjoy implementing many things such as a captcha where we can filter the bots from the people. I am aware that some projects are suffering from spam currently, I am more concerned with someone making a stink about that then the easy use of H2@H. When the security flaws of captcha get worked out on other project and/or it becomes part of our SVN, sure I'll use that.
Again I am only a guy with a Biology background and some moundane IT and I confess to be your intellectual inferior with technology. I only have an idea about hydrogen. I welcome the opportunity to have support from BOINC developers which I currently get from many altruistic people in the community. Gradually you will see the features you want. This is only an alpha project, as such you should not expect everything perfect at first.
I mean my response with no animosity, I'm just trying to describe the way it is. The last thing I want someone to think is I am some kind of snake oil sales man.
