here are some quotes from other forums:
"You will not hold the forum owners responsible for any material transmitted through the site by other users" (this identical wording found on most)
or this "over the top" one
Use of the ___ site, and any information obtained from the service or links to it, is entirely at the users risk. The ___ does not warrant, and hereby disclaims any warranties, either express or implied, including but not limited to warranties or accuracy, completeness, noninfringement, merchantability or fitness for a particular purpose of any information, products or services obtained from the service or a link to it. The ___ does not warrant that the service will operate in an uninterrupted or error-free manner or that the service is free of viruses or other harmful components.
You agree that neither the ___, nor its agents, affiliates, licensees, or third party content or service providers, will be liable to you for any loss or damages, either actual or consequential, including personal injury or death, arising out of or relating to these terms, your (or any third party's) use or inability to use the service, or to your placement of content on the service, or to your reliance upon information obtained from or through the service. In particular, neither the ___, nor its agents, affiliates, licensees or third party content or service providers, will have liability for any consequential, indirect, punitive, special or incidental damages, whether foreseeable or unforeseeable (including, but not limited to claims for defamation, errors, loss of data, or interruption in availability of data), arising out of or relating to these terms, your use or inability to use the service, or to your placement of content on the service, or to your reliance upon information obtained from or through the service, whether based in contract, tort, statutory or other law
I would suggest something like this (I wrote it on the spot)
You will not hold this forum, this forum's owners or any affiliates in any way responsible for the information found in this forum or any information found in any of the internet links found on this forum including (but not limited to) any issues involving accuracy, availability, safety from malicious programming, defamation, suitability of use, copyright infringement, and emotional damage.
