Can you check my sentence? Is this gramatically correct?

Question

WallpaperNow is a gadget that displays beautiful wallpapers to use for your desktop. The gadget is automatically updated everyday and each day a new and fresh wallpaper is selected from our wallpaper database.

Additionally, you can also submit your own wallpapers to us and once we review it, we publish it on our website and make it available for other users.

Thanks for helping me!!!

Answer 1

Period after updated everyday, remove and, capitalize each.  Those are two independent clauses (sentences) and are a run-on sentence as they stand.  You could join them with a colon, but there is no good reason to do so.  Actually, daily would be a better choice than every day.

Second paragraph - Addionally and also are redundant/repetitive/saying the same thing twice, and therefore create mental confusion which distracts the mind from your message.  Again, you have two independent clauses (phrases which are complete on their own).  Period after wallpapers to us, reamove ane, capitalize Once.  No - replace "once we review it" with "After review,"

Answer 2

In paragraph one:  change "everyday" (an adjective) to "every day" (an adverb phrase).  Also place a comma after "day".

In paragraph two:  change "wallpapers" to "wallpaper" (or change "it" to "them").  Also remove the first "and" and replace with a semicolon (;).

Make these changes and you're set!

Answer 3

1st sentence--OK

2nd:  The gadget is updated daily and a new wallpaper is (new wallpapers are ) selected to add to the database.

2nd paragraph:  Users of the database may submit their own wallpapers.  When they have been reviewed and approved, the wallpapers  will be published on our website and made available for other users.
