do posting jokes.. in the laughing category of mylot is allowed..?

yes posting of joke can be allowed but it will get you any earning. As in most of the cases people does not have any thing to response they will read and laugh and say nice jokes . You will not earn anything untill and unless they write a response in few sentences. yes there are certain jokes in which peoples can put their comments nicely and even discuss the matter. that will definately help you. so it depends on material or topic covered in jokes which will make you healthier and wealthier.
happy myloting.

In the Guidelines it states clearly that jokes are not allosed to be posted as discussions.
In the 'don'ts' part it says:

(Don't) Post jokes, recipes, etc. as discussions. This is a form of abuse and all recipes and jokes will be deleted if they are started as a discussion

That does not mean we cannot post funny, humourous things but not jokes. There would be nothing to discuss if a joke is posted as a discussion don't you think?
Happy Lotting!

The Interest categories are not set up by MyLot. They are created by users, so there is nothing 'official' about the Laughing category.

As Mysdianit has said, the Guidelines are there to promote quality discussions. A joke, in itself, is not likely to encourage responses with any substance or quality. The Guidelines should be regarded as helpful rather than restrictive. It is easier and far shorter to give a list of things that are NOT allowed than to list all the things that ARE.

It is true, however, that, when making a topic for discussion, it can be useful to illustrate it and a relevant humorous story or episode may often do that well. That is quite a different matter from just posting a joke. Most people who post jokes merely copy and paste them from emails or the Internet. There is nothing creative or informative about it and that sort of practice is, rightly, frowned upon in MyLot.

Yes, jokes can be posted in this section.
