The 2000 character limit for private messages is rather contraining. Somebody asked me for JCS advice, which I gladly gave, but I had to split it in to 3 seperate messages since I decided to go into detail on a number of things. For me this worked out to about 2-3 paragraphs per message, which isn't a lot.

Is there any reason for having the limit set so low? And if not, why not increase it to the length a normal forum post is allowed to be (which is something like 40k characters)?
