Breaking the day to day

We can discuss this Friday, but I would like to throw out this idea. Normally we play the campaign sort of day by day. I was thinking that for this campaign, it might be better to allow a fairly long span of time go between adventures. We can use this website and email to handle some of the running of the keep, and people can have longer term projects that carry over weeks and months. So for example, we might finish an adventure Friday and then assume a month passes before the next adventure. People can email me if they want their characters to do something.
One advantage of this system is that we could have changes occur at the keep and village in reasonable time frames. Otherwise, it would be fairly unreasonable to expect much to happen over the course of only a few days or weeks.
Another advantage, is that the encounters would be spaced out over time. A couple assaults on the keep each week would be pretty scary, but one a month is not so ridiculous.
Also some personal stuff, research skill acquisition, etc.. Would be easier to explain as well.

I would still want to Role Play any ceremonies or rituals. But we could do that in the past tense if needed.

Let me know what you think.
