I received an invitation of "Modern Sciences Journal" (www.modernsciences.org) on September 1st in order to evaluate my mathematical article. Now I received the notification of acceptation on December 20th and they ask me a pay of 350 USD in order to be published.
I have searched about this Journal but apparently it isn't recognized as a valid scientific Journal nor is it included in the "white lists" of recognized Journals.
On their web page I have searched something about the editors of the Journal, but it doesn't appear anything.
The person that wrote me is called Don Smith ([email protected]) but he didn't identify with any other institution like an University.
I hope some info about this Journal and its reliability.
Thanks in advance.
