Yes there is no problem for me to guide you on the hashtags.

For stories you can use #creativewritings
For Dairy Games use #thedairygame, #lifestyle
For contest use #contest.
On all your posts use #steemexclusive
When you will use your first powerup use #club5050
Use #steemit for the general hashtag.

Depending on the contest that you take in pay attention to the hashtags that they ask you to use.

But in general the #steemexclusive, #cameroon (if you are from Cameroon or Philippines, infact use your country)
