Continue the Blog or not

My sister-in-law wanted to give her blog to me. She’s been using this for a long time. I’m the one who taught her how to do blogging. Now, that she is busy with her offline task she can’t manage her website from time to time. She asked me if I wanted to continue this because it’s  expiring next month. I’m thinking if it wise to continue her blog. I have 5 blogs running and not all of them are managed properly. So, I’m thinking if I will accept the blog or just let it go. Renewal of blog is not cheap compared before and I don’t know if I will be benefited from her blog.  Well, I have still few more days to think. I hope I would come up with the right decision.
