What warnings fo you typically avoid? Which ones do you not mind? Are there any that you look for because you enjoy those particular stories?

None.

But once I've clicked on a story, it doesn't take me long to check if I'll read it or no. If grammar, spelling, reading-friendliness are poor, I'll just back off. Shame there is no warning about that !

I check summaries first. I'm a bit of a grammar/spelling fanatic, so if the summary seems off to me, I probably won't read it. Oh, and once I start pagbaba and people starting using 'internet-speak' like "plz" and "thnx" and "sed" in the story, I'll immediately click out. Anything else written online I'm okay with that, but I can't stand pagbaba it in an actual story. Unless someone's using it to ipakita a text-message or something.
