With those two issues (above in brackets ) either having been addressed, or were already addressed, this opened up the opportunity to submit posts. Any time you submit work to a site you do not own you should, first and foremost, ensure your work and rights are protected. In my opinion, a person should never submit work to a site that claims ownership of your work or does not properly credit the author. The exception being work that you are paid to do for them. If they pay you they have every right to own, and do as they please, with what they pay for.
Of course, if you don't care, or you don't think you have anything of value to submit, then I guess it doesn't matter. But, if you have nothing of value to submit then why would I , or anyone else, even want your submissions? I consider everything that I contribute to another site ( and my own sites ) to have value. Value expressed in content, in time, and effort. So I want that value protected.
Every time you contribute to a site you are adding value to it, value in terms of not only content but also value in time and effort, and the site that is receiving this value should ensure that you get value back in return.
Value cannot be a one-way street, whereby you are giving value and getting nothing for it. The exceptions to this rule are family, friends, and charitable endeavours; where the value you give is out of love, compassion, etc...and there is no demand or expectation that it must be returned.
