Yes, you do have a problem. I would suggest the best option for you to use would be to use the html <iframe> tags. It would work like so:
Get yourself a new page set up (the one you want to board to be on), keep the design as you normally would for all your other pages, then it the right hand side content column add something like this:
Code: Select all
<div><iframe src ="link to board location in here"width="600px" height="400px"></iframe></div>
Now with the code above you will need to use some accuracy, so you will first need to edit the "src" reference to the location of your phpBB, adjust the height and width dimensions also so that it does not break your page layout. This will give you the effect you are looking for.
The downside to this will be that you will need to compensate the expanding height of your phpBB with scroll bars, but none the less it is still and effective result.
