Hello~
I'm a new member on the site, so I thought I would post in the forums and meet some new people.
I've watched OHSHC, Fruits Basket, Clannad,(Not sure if these three are on Funimation or not) and Hetalia( 
), but I'd really like it if a few people could recommend some other shows! 
What other good ones are there?
Welcome to FUNi! I'm kinda new to the forums, too, but some shows you may like (if you haven't watched ~After Story~) Angel Beats!, Spice and Wolf, and I've heard Air is good, but I haven't watched it yet. If I think of any more I'll let you know!
Greetings Forever Young.
Welcome to the Funi site/forums. OHSHC is On the Funi site and so is Fruits Basket. Clannad is a Sentai titles so its not here. But if you liked Clannad you should check out Kanon. And yes its also on the site. 
Anywho hope you enjoy your stay. 
I reject your reality and replace it with my own.
Welcome to the forums; hope that you post a lot around here.
If you are looking for some anime recommendations, here are my suggestions: School Rumble, Samurai 7, Bamboo Blade and Shingu: Secret of the Stellar Wars.
If you are interested, don't forget to check out the link in my sig about requesting the FUNimation Channel.
Welcome to the site. And Air is an excellent series in my opinion. I think both you and Bugfish might like it.
"When you truly care about someone, you don't need any specific reasons to justify your feelings. If you don't know why you feel the way you do, then you can't lose that which causes you to care."
Wow thank you for all the recommendations everyone! I'll be sure to check out the shows you all suggested!
WELCOME 2 THE FUNi FORUMS
Here are some series that are similar to the ones you've listed and they are : K-ON! ~ School Rumble ~ Tamako Market ~ Toradora! ~ Hyouka
Hi F-Y! To take you in another direction, Highschool Of The Dead and Shiki are good, if you like the horror genre
Which you apparently don't mind, with The Walking Dead - nice
I'm right behind you...
