Every lens is different right? Of course, that is why Squidoo is what it is. The very uniqueness is what makes it work. I will treat each lens for submission "basically" the same way Squidoo does. Below are the requirements that I could think of that make a lens a quality lens.

1. It needs to be complete:
(A) Complete for me is not complete for you. You may have only a few modules in your lens and that is all you wanted or needed to complete your lens. I can appreciate that, however, based on the "quality of content" and "quantity of content" of that lens, I will decide if the lens has enough of "both" to be considered complete.
(B) Please do not submit a lens with unedited modules, because I will reject it. Be sure and check and delete the unfinished module. Then submit the lens. I will not reject a lens if it has only two or three modules for reasons I stated above.
(C) Grammar and spelling: I do not profess to being an English major or professor. But I'm not a dim-wit either. If you suffer from poor grammatical and/or spelling skills then use Word or some equivalent to proof your documents before adding them to your lens. I won't shoot down a lens for a typo or one or two missed spelled words, but they will be rated accordingly. And I will always tell you why. As I would have you do for me as well.
(D) I would have everyone rate each other the same way. Consistency is key in a group such as this so folks will always know where they stand. So if you come across a lens created by me, of course you would automatically give me 5 stars right?...Hell no! Rate me the same way I have explained things here. I will not submit a lens for rating unless it has passed my own standards of completeness.
(E) Which brings me to the next thing: I would like to create different levels for folks to submit their lenses to. For example; if a new lensmaster wants to submit a lens, then I would like for that person to be able to submit their lens accordingly, and be rated as such. I could not in good conscience rate a new lensmaster based on the same standards as one who is experienced and may have many lenses under their belt. It wouldn't be fair, and I would hope others would take that into consideration as well.

That is really all I could think of to begin with. If you can think of something I missed then by all means let me know.
I hope you will find fair and balanced rating here.
