Ending an art competition sooner than originally planned?

[Daniel]

Note: I couldn't find any of this on the stickies, so sorry if I skipped something saying it; I did look ;=;

I have a particular contest going on.
It started on the 1st and was meant to end on the 20th.
However, I have received a large number more entries already than I previously expected.
Although lovely art, I fear I may get to a point where I end up having to add so many runner up prizes I have no pets at all xD

Due to this, would I be able to end it, say, 5 days earlier, so it ends on the 15th?
I would inform the people, straight away, who are currently still in the process of making their own entries, that the contest would be ending sooner. I would also make a new date saying it is ending on the 15th, and I would make a few posts on the board letting anyone else who may have previously bookmarked that the ending date is now sooner.

Prizes would not be effected in any way.

^
Much more complicated than I meant it to be.
Let me sum it up:
Can I end my contest sooner than originally stated, or is this against the rules?

that's fine as long as you make sure everyone is made aware of it several days before the closing time

Ah, lovely!
Thank you, Tess.
I had a feeling it was against the rules for some reason o.o;
