What do you dislike about ResearchGate?
Their registration layout tries to be fancy by "Oh. Look how smart I am, just give me your institutional e-mail address, and I'll find your colleagues". "Oh you did gave an institutional e-mail which I don't recognize? Please wait request a free account, and wait for the 459 requests ahead of you."
This basically happened to me. A year ago, the institution I'm working in changed name, thus my e-mail changed, which Researchgate didn't recognize... Ok. I've waited to complete the requests in front of mine. After 10-20 minutes I was able to verify myself as a researcher. At least that was what I thought. I needed to provide an URL of one of my publication, and then guess what? "We have received your request and will get back to you soon."
Still waiting while writing this review... I've never experienced a registration process being such a hassle. I hope that after this request I will finally be able to use this for what I originally wanted. But I wouldn't be surprised if they would be asking for a birth certificate and blood sample...
And this leads us to my next point. I wanted to get a very old post from a project log. There is no possibility to search in a specific log. You have to scroll all the way back. But after 2-5 minutes of vigorous scrolling, they will "notice unusual traffic from your network", dropping you back to the newest post of the project log. 5 minutes wasted. After this you can go a bit further, then it drops you back again. Eventually, you will need to check a checkbox to "validate yourself", but the checkbox doesn't appear for me, and couldn't do anything until clearing the cookies.
I hope that registration solves this issue. But seriously, this is one of the worst systems I've ever needed to use.
PS: I've started the registration process 30 minutes, for now, still not being able to log in... All this because Researchgate failed to update its list of institutions, and catching up with the fact that "Hungarian Academy of Sciences Wigner Research Centre for Physics" is only "Wigner Research Centre for Physics" now, and the e-mail domain is not @wigner.mta.hu, but @wigner.hu.
