For me - I think there are just too many 'challenges' now, to go through them all would be a full time job. So it is either view the gallery of challenge entries that has grown in the forum or view the normal gallery, there is not time to enter and comment on all.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
