Wow...lot of R in this post's title...XD;
Anyway, since the beginning of this summer I've been reading Ranma 1/2 online and re-reading it too. In case that makes no sense, it's because I used to read the manga out of order. (my old high school's library had some volumes but jumped all over, ex. they had volume 1-4 but not 5-15, and had 16 but not 17-28 and so on)
So, I've read some chapters previously online or the actual volume (but like to read them again anyway) and some I've never read before. It's a bit confusing at times exactly where I am. (although myanimelist has solved most of that problem)

I'm actually happy that I never finished reading the whole manga. I love running into chapters I've never read before after re-reading something. :D It's a nice surprise. -no regrets!- I love the manga, though the random nudity from female!Ranma can get a bit creepy/annoying when it just pops out of nowhere. 
Still, very good manga to read or re-read. Some stories aren't multi-chapter ones (and some are, but aren't too long), so it's fun to read when you don't have anything else to do or during a break.
