Dear colleagues, Every week, I receive an invitation "from one of you" to join ResearchGate, whatever this is. And some of you may receive invitations "from me". I have been ignoring these e-mails, but am getting more and more annoyed. There are some people out there building up a data base, which they will next sell to interested parties, such as commercial publishers. What they are doing is probably illegal, in the sense that, for example, they are claiming to write "on Joyal's behalf" in the case copied below. I believe we should do something about this. Do we have a legal expert in our midst? Are we going to claim our share when they sell? I'd be interested to hear your opinions. Ieke. -------- Original Message -------- Subject: Reminder: Joyal Andre and 1 other invited you to join ResearchGate Date: Thu, 17 Apr 2014 11:42:24 +0000 (UTC) From: Joyal Andre <no-reply@researchgate.net> To: i.moerdijk@math.ru.nl ResearchGate [profile_default_m.jpg] Your co-author Joyal Andre invited you to join their network on ResearchGate and confirm authorship of your publications.
