Still having difficulty converting Shadow to SDC. The buttons in the wallet are ambiguous and there is no clear procedure; also unclear is the relationship between stealth and open addresses. That's something that really needs to be a priority for the secrecy aspect of the coin to be useful- we need a wallet upgrade with the SDC-Shadow addressed.
When converting Shadow to SDC this is what I do at the moment. Because there are few Shadow in the network (less than 1%) the amount of available inputs/outputs is very small compared to what it will be soon. Therefor I inspect the Chain Data section of the wallet and pick an available System I/O value close to the amount I wish to convert.
Say you have 552.3245 Shadow you wanted to convert to SDC, then I would send 550. This would go through no problem. As I say we wont have to think about this as the amount of Shadow increases.
Now before sending 550 i click the button "suggest ring size". this will change the ring size value automatically and it should now send without a problem.
Additionally my feeling is you should always leave some dust Shadow amounts even if u wanna convert all to SDC and cash out. These dust amounts (e.g. 0.5423) will improve the systems overall anon by confusing SDC>Shadow>SDC even more (in my opinion anyway).
A tutorial would be useful and Im sure members of this community could produce some good ones

Reminder: Convert more SDC to Shadow.
Reminder: Its all about Shadow to Shadow.
