Manga Fox is a very clean and easy to use site. Over 4500 manga series, over 68,000 chapters–you are likely to find something you like in every genre. There’s also a really active forums.
Look in the drop down box for the series you want. You’ll get a description, you’ll see latest entries in the forum for that series, and scroll under that to see the scanlations. All viewing is within your browser and they upload FAST (so consider sending them a donation for their servers!)
Can’t recommend this site enough.
