So this is going to be a master list of grammar tips for you to use to improve your content. I know personally that horrible grammar really grinds my brains, so I'm hoping you guys will review this thread and help raise the quality of articles online!

Subject Verb Agreement:
The amount of the subject must agree with the verb tense. Examples:

"She runs away" is incorrect. "She ran away" is correct.
"He buy many sites" is wrong. "He buys many sites" is correct.

Verb Tenses:
The verb tense must agree with the time period of the content.

Present:
"Learn about webmaster" is wrong. "Learn about webmastering" is right.

Past:
"Learned to webmastering" is wrong. "Learned to webmaster" is right.

Future:
"Learn to webmastering" is wrong. "Learn to webmaster" is right.

Apostrophes and Pluralization:
You NEVER use an apostrophe (') to pluralize words. Apostrophes are for showing possession. Examples:

Blog's (plural) is wrong. "blogs" is correct.
Blogs posts (possessive) is wrong. Blog's posts correct.
