Try and look back at my mail where i mentioned how to apply for MPNP. You will have to write a letter of interest to choose manitoba as your destination, fill in online form supported with the requested documents and request for a Letter of invitation to Manitoba. If you receive this letter, then you can submit the letter to accra, There you go, you will get your visa less than 6 months.
YOU SHOULD ALSO NOTE THAT APPLYING FOR MANITOBA MEANS YOU ARE NO MORE WISH TO IMMIGRATE UNDER FSW BUT PNP. You only land in manitoba and live there for 3 years before you can move to another destination
The backlogs issue only apply yo pre 2008. If you are pre june 2010 you will still be selected for FSW
