If you're looking for a webhost that supports activeCollab, check out Dreamhost. They allow you to install activeCollab with "One-Click" from within the control panel and your activeCollab install is ready in literally about 2 minutes.

Oh yeah, they also have unlimited subdomains and domains on each account, so you can install as many as you want. I am giving it all of my web-design clients as a free "bonus" to add value to my business. It's not likely that you'll ever run out of disk space, since they add several more GB every week to your account!

Plus, it's only about $8 a month! (can you tell I'm a satisfied customer?) But if you enter 555DEAL in the 'promo code' field, I think the 1st 2 years are only $5.55 per month (but you have to pay for 2 years up front).

Anyways, I've never, EVER been more satisfied with a webhost, so I figured I'd pass along the info in case you're looking!

Yes, Dreamhost is shared. If you've got your own server running, go for it! Why pay someone else to host it, especially if speed is not important to you. I am a professional web designer, so I MUST have speed for my clients' websites. Someday though, it would be nice to have my own server and sell the webhosting space to my clients...

But until then, I am totally happy being blown away by Dreamhost's service. Recently they QUADRUPLED my disk storage space up to 200 GB! I've never had a company offer me substantially more value, without upping their prices.

1: WLM -> Bit of a spammy posting I'd say, as you're obviously promoting your own referral code (referrers to DH are well paid).

2: The great support DH now offers will not continue once aC is no longer open-source. Of course youll still be able to install it yourself, but they only offer the super easy one-click installs for open source apps.
